CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 276,289, dated April 24, 1883. Application led January 2, 1883. (No model.)

To all whom it may concern: Y

Be it known that I, ANDREW S. HALLIDIE, of the city and county of San Francisco, State of California, have invented an Improved Gable Railway; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in cable railways iu which an endless rope travels in an underground slotted tube or tunnel and serves to propel the cars which run upon the track ou the surface ofthe ground by means of a gripper, which has a shank extending from the car through the slot into the tube.

My invention consists iu a novel construction of a cellular metallic covering for the tube, having a filling of wood or asphaltum,

which provides a secure footing for horses, in place ofthe broad and slippery surface of iron, which is usually necessary to keep the sides of the slot from spreading. This cellular covering forms also a rigid boundary Vfor the slot, in place of the irons ordinarily employed.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a transverse section of my device at one of the yokes. Fig. 2 is a` plan of my device; and Fig. 3 is a vertical section at the line a: :i: of Fig. 2, between the yokes.

A A are the sides and bottom of a tube, which is built beneath the surface of the street to ,inclose and protect a traveling cable, B, which runs within it. This tube is supported and strengthened by transverse standards or yokes (l, which are usually placed at intervals of about three feet.

D is the slot at the top, through which the shank of the gripper passes. This slot has been formed 4by strong bars of angle or T iron, which are fixed upon each side and suiciently separated to form the slot. Theseiron bars present a smooth surface of considerable width, upon which horses are apt to slip and become injured.

In my invention I employ a cellular structure, E, which may be made of cast-iron or other material of suihcient strength, in suitable lengths, which may be bolted or otherwise secured to the yokes or standards G, and which bridge the space between the standards C. The cells extend a short distance `upon each side of the slot D, and the bolts by which they are secured may pass down through the bottoms of the cells into the yokes. By removing these bolts any one or more of the sections can be removed, and the tube will be open for iuspection or work of any kind without in any way disturbing the street-paving;- The cells are filled with wooden or other blocks, asphaltum, concrete, cement, or any substance which, projecting' slightly above the boundaries or sides of the cells, will provide a secure and elastic footing for horses, while the cellular structure below is rigid aud strong enough to preserve the shape of the slot and prevent its being either compressed and closed or spread apart.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cable railway, and in combination with the underground slotted tube or tunnel, the metallic cellular.coveringpieces E, substantially as herein described.

2. Acast-iron or metallic covering-piece having cells lled with asphalt, concrete, wood, or

similar material, in combination with the tube of a cable railway, substantially as herein described.

3. A cellular metallic covering for the tube of a cable railway, arranged toI form the sides of the slot or longitudinal opening through which the shank` of the gripper passes, and

made removable without disturbing the paving of the street, substantially as herein described.

4. .The combination of the cellular coveringpicces E with the yokes C and the tube of a cable railway, substantially as herein described.

In witness whereof I hereunto set my hand.
